  Expiry Date: Apr 09,2018
  Detailed Description: Cas No. :37971-36-1 1,Properties:
PBTCA has low content of
phosphoric, has structural
features of both phosphoric acid
and carboxylic acid group, which
enable its excellent scale and
corrosion inhibition properties
and better than other normal
organic phosphorus acid,
especially under high temperature
its antiscale property is far
better than that of normal
organophosphines. It can improve
zinc salt solubility, has good
chlorine oxidation tolerance and
good composite synergy.
2, Specification:
conform to HG/T 3662-2000

3, Usage:
As high-efficient agent of scale
and corrosion inhibitor, PBTCA is
one of the widespread used and
good performing products. It is
the excellent stabilizer for zinc
salt. It is widely used in
circulating cool water system and
oilfield refill water system as
scale and corrosion inhibitor,
suitable to composite with zinc
salt and copolymer. It can be
used in situations of high
temperature, high hardness, high
alkali and high concentration
index. In lavation fields, it is
used as chelating agent and metal
detergent.
4, Application range&using method
PBTCA is usually used together
with zinc salt, copolymer,
organophosphine, imidazole and
other Water Treatment Chemicals.
When used alone, the dosage of 5-
15mg/L is preferred.
Package and Storage:
Normally In 25kg or 250kg net
Plastic Drum, Storage for
twelvemonth in room shady and dry
place.
Safety Protection:
PBTC is Acidity, Avoid contact
with eye and skin, once
contacted, flush with water.
